The invention relates to valve fittings designed for use as pet cocks, priming cups, feed line valves, etc., and consists in the construction as hereinafter set forth.

ln the drawings:

Figure i is a longitudinal section of a construction designed for a feed line;

' Figure 2 is a section on the line 2--2 of Figure l.

Figure 3 is a se lil :lli

ction on the line 3-3 of My improved tting comprises a substantially llshaped member A having a longitudinal bore B therethrough, and an intersecting bore C through the stem of the '"l`.

25 rlhis intersecting bore is formed with a tapering inner end, so as to produce a conical seat D intersecting the bore B and having a slight clearance at its apex, as indicated at 1E. l? is a valve stem having a threaded enso gagement with the bore C and provided with a conical end portion Gr corresponding to the conical seat D. rllhe arrangement is such 'that Serial No. 34%,@ 7d.

when the valve completely close ing the valve aw may be opened restriction.

As shown in Figure l, the stem ll is vided with a handle H an I is arranged at the oute portion of the casing A. also shows one end of the ing a threaded nipple end provided with a co ment to a pipe line L.

Vl/vhat I claim as my invention is;
